Jake Shields insists Nick Diaz will not walk away from MMA, despite his temporary suspension dished out by the Nevada State Athletic Commission.

Diaz recently tested positive for marijuana following his fight with Carlos Condit at UFC 143, and will now be temporarily kept out of the Octagon while the NSAC conducts an investigation.

However, if the fighter's words are to be believed Diaz has already retired from the sport, insisting after his controversial loss to Condit that he was "done" with MMA. A unanimous decision went against Diaz, and his sheer disgust led to a knee-jerk reaction inside the Octagon.

Shields, one of Diaz's main training partners at Cesar Gracie Jiu-Jitsu, is confident that the Stockton brawler was only venting his emotions, and he predicted Diaz will be back once his suspension is lifted.
